BELTING AND METHOD OF MAKING THE SAME.

Application filed July 5, 1917.

To all whom it may concern:

Be it known that I, BENJAMIN T. STRING, a citizen of the United States, residing at Norwood, .in the county of Hamilton and 1 My invention relates to an improved belting made of textile material, for example, canvas, and to the method of making the same.

It is the object of my invention to provide a new and improved textile belting, capable of withstanding reat stress; further, to provide a new an improved textile belting which-is substantially round in cross-section, and adapted to form a substitute for round leather belting; further, to provide a novel belting of textile material comprising a strip arranged in folds and stitched in novel manner to form a belting of substantial thickness comparative to its width, and, further, to provide a new and improved method for forming the belting and for finishing the same.

The invention will be further readily understood from the following description and claims, and fromthe drawings, in which latter:

Fig. 15 is a cross-section, taken on the line 15-45 of Fig. 1, showing the completely folded, stitched and stretched belting.

My improved belting is preferably formed from a textile strip, exemplified at 21, which may, for example, be a strip of canvas.

In the primary operation on the strip, one

margin of the strip is folded inwardly upon the body of-the strip for forming the fold 22, creased along the crease 23. The other margin of the strip is also folded inwardly upon thebody of the strip, forming the fold 25, creased along the crease 26. The inner edges 'of the folds overlap each other as shown at 27. The folding may be accomplished by a folder 28, having the folding wings 29, 30, for respectively folding over the folds 22, 25.

U on the folding of the primary folds, the olded strip is provided with a line of stitchin 31, lengthwise of the strip, which passes t rough the superposed inner edges of the folds 22, 25, and the.body of the strip, along a proximately the median line of the strip. he stitchingor seam thus formed lengthwise of the belting is pr ferably a lock stitch, formed of two throds 32, 33, which interlock one with the other for forming a lock stitch locking the sewed parts together, and extending lengthwise of the belting for aiding in strengthening the tinished belt.

The stitching maybe formed by any suitable means, as by aiiy suitable sewing machine, preferablv aaloclostitch sewing machine, the nsualiii-esserfoot 34, piercing needle 35. work support 36, intermittent feed'bar 37, and rotary hook 38, of the sew ing machine being exemplified in Figs. 1 and.

6. The forward feeding of the strip is instanced accomplished automatically by the sewing machine. which feeds the strip through the folder 28 and past the sewing instrumentalities.

When the primary folding and stitching of the textile strip has been accomplished, the primarily folded and stitched strip is passed through a second or intermediate folding and stitching, or sewing operation, which may immediately follow the primary folding and stitching, as a continuous operation, as exemplified, or may be accomplished subsequent to the finishing of the primary folding and stitching as a separate operation or operations.

The intermediate folding and stitching serves the purpose of folding the margins of the primary folds toward each other, and arranging them in separated relation, so as to facilitate subsequent folding of the partially formed belt. The margins of the primarily folded strip are folded inwardly toward each other by a folder 41, having the folding Wings *2, 4.3. for respectively forming intermediate folds 44, 45, along the respective margins of the primarily folded strip, along intermediate creases 46. ii. in such manner that the inner or proximate edges of the intermediate folds are separated by the space 48.

Stitching 51.52. is passedthrough tbeintermediate folds, preferably along ,their inner edges. and through the primary folds and body of the partially folded belting. this stitching being instauced as accomplished by a suitable two-needle sewing machine. sewing two lines of stitching along the respective inte-rn'iediate folds. preferably adjacent their inner edges. the parts of the two-needle sewing machine being exemplified similarly to the parts of the sewing machine accomplishing the primary feeding and stitching, with similar parts identified by similar reference numerals raised to the series 100. The stitchings' 51, 52. are preferably two'thread lock stitchings similar to the stitching 31.

\Vben this intermediate folding and stitching has been accomplished. the partly formed beltim will have the intermediate form exemplifii-d in cross-section in Fig. 1:2.

The partially formed belting in the intermediate form. is next subjected to an additioual folding and stitching operation which may be accomplished immediately after the intermediate folding and stitching as a continuous operation, as exemplified. or

' subsequent to the completion of the intermediate folding and stitching of the entire strip as a separate operation or oierations. In theprescnt exemplification. the subsequent folding and stitchingis shown accomplished as a continuous operation on the strip, while the. intermediate folding and stitching is being performed thereon;

upon the other. The subsequent folding arranges all of the lengthwiseouter edges of the strip, and the inner edges of the intermediate folds in the inside of the completely folded strip, so as to present continuous woven fabric devoid of outer or cut edges at all outer surfaces of thebelting. The superposed folds formed by the subsequent folding, have a stitching 60 passed therethrough. this stitching being preferably a two thrcad lock stitching. similar to the stitching 31. formed by a sewing machine. the parts of which are similar to the other sewing machines instanced as employed. but preferably of stronger structure, similar parts of the machine being indicated by similar reference numerals, raised to the series 200.

The belting thus formed by the folding and stitching is exemplified in crosssection in Fig. 14.

The belting is preferably permeated with a preserving or seasoning compound, which may be exemplified as comprising bees-wax and animal fat, or may be any suitable belting composition. which is preferably heated when applied to the belting. The application of the heated prescrvant to the belting. may be accomplished by passing the belting through a bath. exemplified at 61, in a tank 62. in which the bath may be heated in suitable inanner. The belting may remain in the bath long enough to be permeated to the desired extent by the preservant. In passin through the bath the belting is receiver about directing rollers (i3, 64, 65. 66, suitably supported.

When the belting has been folded and stitched as hereinbefore described, it is of a substantially great thickness compared with its width. the upper and lower surfaces of the belt. however. being still somewhat flat. In order to give the beltin" a round form, or a form which in cross-section presents only one comparatively flat surface, the belting is passed between suitable rollers, three sets of rollers being exemplified at 67, 68; 69. 70; and T1. T2.

The peripheries of these rollers are protank 62. v

The sets of rollers are preferably so'geared, that the rollers 'of' subsequent sets will rotate at greater peripheral speeds than preceding sets.

Thus a drive-shaft 75, driven in suitable manner, as by a pulley 76, has a gear 77 fast thereon which meshes with a car 78 on a shaft 79. The shafts 75 and 9 are journaled insuitable bearings in a frame 80. The gears 77 and 78 respectively mesh with gears 81, 82, faston shafts 83, 84, on which the rollers 71, 72, are secured. The shafts 83, 84, are journaled in bearings 85 adjustable toward and from each other by setscrews 86, 87, the bearings being slidable in guideways 88 in theframe 80. The gears 81, 82, mesh with transmitting gears 89, 90, rotating on studs 91, 92, secured to the frame 80. The gears 89, 90, mesh with gears 93, 94, fast on shafts 95, 96, to which the rollers 69, 70, are secured. The shafts 95 96, are relatively adjustable and are mounted similarly to the shafts 83, 84.

The gears 93, 94, are larger'thanthe gears.

81, 82, for rotating the rollers 71,72, at greater peripheral speed than the rollers 69, 70, for stretchin 'the belt passing between said sets of rol ers. The 'ars 93, 94, mesh with transmitting gears 9 98, rotating on studs 99, 100, secured to the frame 80. The transmittin gears 97, 98, mesh with gears 101, 102, ast on shafts 103, 104, to which the rollers 67, 68, are secured. The gears 101, 102. are of greater diameter than the gears 93, 94, for rotating the rollers 69, 70, at greater peripheral speed than the peripheral speed of rotation of the rollers 67 68, for stretching the belting. The shafts 103, 104:, are relatively adjustable and are mounted similarly to the shafts 83, 84.

The rollers 67, 68, 69, 70, and 71, 72, press upon the beltin during their action,

thus subjecting the be ting to stretching, the

result being that the belting is rounded and stretched during this operation. The form of the finished belting is exemplified in cross-section in Fig. 15.

Havin thus fully described my invention, what I c aim as new and desire to secure by Letters Patent, is

1. The method of making textile belting whichconsists in folding the margins of a textile strip toward each other as primary folds, folding said primary folds toward each other for forming intermediate folds along creases whereby the outer edges of said primary folds are presented toward each other, assing stitching throu h the said interm iate folds and the b0 y portion of the strip, then folding the bodyportion of said strip'along the median line of said body ortion for folding said intermediate olds upon each other in manner to inclose one of the faces of all said stitth' ings within said folds, assin stitching throu h said intermediate olds or'connecting t e same, and subjecting said folded and stitched product to edge pressure directed in the plane of the width of the strip for cross-sectlonally. shafilng the same.

2. The method of ma in textile belting which consists in folding the margins of a textile strip toward each other as folds whose inner edges overlap each other at the middle of the body portion of said strip, providing the folded strip with a stitching through said overlapping edges and said body, folding'the folded margins of said prim'ar folded strip toward each other on the si e thereof where said overlapping mar ins are located for forming intermediate olds along creases whereby the outer edges of said primary folded strip are resented toward each other in coinci ent lanes but spaced apart, for forming a space etween them, passin stitchin through the said intermediate f0 ds and t e bod por tion.of the strip, then folding the b0 y portion of said strip along the median'line of stitching through said intermediate fol s for connectin the same, impregnating said folded and stitched product with a preservant, and subjecting said product to stretching and ed e pressure in line with the planes of said fo ds for cross-seotionallyshaping the same.
